CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 415,623, dated November19, 1889.

Application filed September 16, 1889. Serial No. 324,043. (No model.)

To aZZ whom, it may concern:

Be it known that I, ROBERT I-I. DOWLING, a citizen of the United States,and'a resident of Newark, in the county of Licking and State of Ohio,have invented certain new and useful Improvements in Devices forCoupling Cars; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letteis of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a side elevation. Fig. 2 is a bottom view.Fig. 3 is a horizontal section. Fig. 4is a top plan View, and Figs. 5,6, and 7 are detail views.

This invention relates to certain improvements in car-couplings; and itconsists of the novel .combination and construction of parts, as willfully appear from the following description and accompanyingillustration.

In the embodiment of my invention I employ a draw-head A, having acurved or concave front end or face, one side of which terminates with abeveled extension or. The other side of said end of the draw-head A isprovided with disk-like extensions 1) orlugs, one at top and one atbottom, and between these lugs or extensions is an opening c, forming aseat for the knuckle or hook, the surface or wall of said opening beingconcave, and having the portions or surfaces immediately adjoining thedisk-like lugs or extensions 1'), however, formed in the arcs of truecircles to provide bearings c c for said knuckles or hook. The openingor seat 0 merges or terminates in the knuckle or hook receiving chamber0 of the draw-head A.

B is the knuckle or hook, the beak of which stands nearly parallel withits inner tapering or tongue-like portion B. Said knuckle is formed witha cylindric portion or axis 1), which rests or bears upon the hearingsor arcs c of the draw-head A, said axis or cylindric portion being ofless width than the hook or knuckle, thus leavingbearing-surfaces (1 clupon the latter, having curvatures concentric with and engaging thefront edges of the disk-like extensions or lugs Z) of the drawhead.

Through the cylindric or axial portion 1) of the hook or knuckle l3 andthe extensions or lugs b is inserted the axial pin O, upon which thehook or knuckle is carried, said pin having a spline-and-slot connection0 6 therewith, but serving to pivot the hook or knuckle in thedraw-head.

The extreme inner edge of the tongue-like 6o portion B of the knuckle orhook 13 engages a buttress-notch f in one side of the chamber of thedraw-head A, and transfers the resistance from the knuckle or hook tothe drawhead. This end of the tongue-like portion 13 of the hook orknuckle B is also adapted to swing in alignment with the coupling-pinopening g in the draw-head, in order to engage an inclined shoulder h ofthe holding pin D. When the holding-pin D is in a lowered position inthe draw-head A, the lower edge of the inclined shoulder it rests uponthe bottom of the hook or knuckle receiving chamber 0 and should theknuckle or hook be in its uncoupled position or swung outward, thetongue-like portion Bof said hook, in event of contact therewith of thebeak of the hook of an opposite draw-head, will be pressed inward, and,engaging said shoulder, will carry said pin upward as it is passing 8oinward until said tongue-like portion passes said shoulder. Immediatelyafter this the pin will automatically fall and prevent the returnmovement of said tongue-like portion of the hook or knuckle, and thuseffect the automatic locking of the coupling-knuckle.

The inner or rear side of the tongue-like portion B of the hook orknuckle B has about midway between its inner end and axis or cylindricportion a hooked projection or tooth 0 i, which engages a correspondingnotch or recess t" in one side of the chamber 0 to effect theinterlocking of the knuckle or hook B with the draw-head, whereby theknuckle or hook will be prevented when in its closed 5 position frombeing withdrawn, even though its pivoting-pin should become displacedfrom the draw-head chamber.

The knuckle or hook is readily. operated, so as to permit the uncouplingof the cars I00 from one side of the latter by means of the hand leveror rod H, which is loosely c0nnected at one end to a shoulderedplate-like bar j, passed through a transverse aperture j in the lowerprojecting end of the pivoting or axial pin 0, to which it is held byits shoulder, and a small key passed transversely through said pin. Therod or lever H also 5 passes through a slot K in the lower end of thepin D, in which it has a limited play, and engages when the knuckle orhook is in its uncoupled position in order to hold it in that position.A hook I is provided upon the unro der side of the draw-head. The rod orlever H extends outward sufliciently to be 0011- veniently grasped andoperated.

Having described this invention, what I claim, and desire to secure byLetters Patent, I 5 1s 1. In a car-coupling, the knuckle or hook havingthe extreme inner end of its tonguelike portion engaging a notch orrecess in the wall of the draw-head chamber, said notch being arrangedin rear of said inner end of the tongue-like portion, substantially asset forth.

2. In a car-coupling, the knuckle or hook having upon its inner or rearside between its inner end and axis a hooked projection or stud engagingor interlocking with a corresponding notch in one side or wall of thedraw-head chamber, and the draw-head having a notch in rear of andengaged by the extreme inner end of the tongue-like portion of theknuckle-hook, substantially as set forth.

3. In a car-coupling, the holding-pin having an inclined shoulder andriding in an opening in the draw-head, the lower edge of said shouldernormally resting. upon the bottom of the draw-head chamber, incombination with the hand lever or rod having a looselyconnected bar orlink connected to the axial ing-pin, substantially asset forth.

4. In a car-coupling, the knuckle or hook having beyond its cylindric oraxial portion concave bearings or shoulders engaging the 5 front edgesof disk-like portions on the draw.- head, substantially as set forth.

5. In a car-coupling, the knuckle or hook having the inner tongue-likeportion adapted to move in alignment with the coupling-hook the lowerend of the hook or knuckle pivot or axial pin, said rod passing throughthe lower end of the holding-pin and engaging a hook upon the under-sideof the draw-head, substantially as specified.

7. The combination of the draw-head, the

knuckle or hook having a tongue-like portion adapted to move inalignment with the holdling-pin openingin the draw-head, the pivoting oraxial pin connecting the knuckle or hook to the draw-head, theholding-pin hav- 7o ing an inclined shoulder having its lower edgenormally resting upon the bottom of the draw-head chamber, and the leveror rod having a loose bar connection with the loose end of thehook-pivoting pin and passing through the lower end of the holding-pinand engaging a hook on the under side of the draw-head, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.ROBERT H. DOWVLING. Witnesses:
